The Model 3 Performance model didn't include Track Mode when it was first introduced. Tesla added the initial offering of Track Mode in late 2018.

Tesla later released Track Mode V2 as a software update.
The Model S Plaid was introduced in the summer of 2021. Similar to the Model 3, Track Mode wasn't available at launch.
With software update 2021.44.30, Tesla is rolling out Track Mode to the Model S Plaid.
Adjust Handling
Track Mode lets you fine-tune your vehicle's settings and disable or tone down certain features such as traction control.
Track Mode in the Model S offers similar capabilities to the Model 3. It lets you adjust handling, traction control, and regenerative braking.
The car will also make other adjustments. When Track Mode is enabled it will precondition the battery for peak performance and will increase brake cooling.
If the vehicle is unable to cool the brakes sufficiently, it will warn you with a 'critically high brake temperature' warning.

Visualizations
When Track Mode has been enabled the visualizations in the instrument cluster will also change to display additional details about the car.
The visualization will show the internals of the car; similar to the charging screen. It'll display the chassis of the vehicle, the wheels, brakes, motors, and battery.
Each item in the visualization is colored to give you feedback for the specific item.
For example, the Model 3 Performance will turn each wheel green, yellow, or red depending on the wheel's traction.
There is also a visualization for G-forces that's similar to the Model 3. It'll display the direction and amount of G-forces.

Lap Times and Recording
In addition to customizing how the vehicle handles, the increased performance cooling, and the visualizations, Track Mode also includes some additional features.
Track Mode will let you set start and finish markers on the map. When these markers are set, the car will automatically display lap timings and record each lap through the car's cameras.
The cameras used during track mode are the same ones that are available when using the Dashcam. However, when using Track Mode, the car will automatically save each lap as a separate video to your USB drive.
Presets

When you customize the handling of the vehicle, you will also be able to save the settings and give them a name.
You can have up to 20 different presets for various conditions or events. The vehicle comes with two presets, one for racing and for drifting.
Here is a fantastic video of Track Mode in use on the Model 3 Performance.
Release Notes for Track Mode
The release notes for Track Mode in 2021.44.30 discuss some of the features available in Track Mode.
Optimize your Plaid configuration for dynamic driving exclusively on closed courses and experience the unmatched performance at many different venues. To enable, tap Controls > Pedals & Steering > Track Mode.
- Thermals: The heat pump system cools more aggressively, maximizing powertrain endurance and performance. Enable post-drive cooling to shorten wait times between sessions.
- Drive Systems: Torque vectoring authority is increased across the three motors, elevating the vehicle's agility and cornering capability. The accelerator pedal allows more precise torque control, and regenerative braking power is strengthened to recover more energy.
- Suspension: Adaptive damping reduces vehicle motions, improving handling and promoting driver confidence. Ride height is automatically set to 'Low' upon drive off.
- Display: A track-focused interface includes a lap timer, G-meter (real-time accelerometer), vehicle thermals monitor, Dashcam video capture, vehicle telemetry capture, and offers customization options.
Tesla’s been on a roll with Supercharger improvements lately, from the 325kW charging update for the Cybertruck, to 500kW with V4 Superchargers coming next year. While those improvements have been limited to the Cybertruck, Tesla didn’t put all their focus on their new flagship vehicle, but looked at their more affordable vehicles as well.
LFP Battery Heating
Tesla’s Superchargers can now heat LFP Batteries - those that are in the Model 3 and Model Y Rear Wheel Drive variants. This applies to Long Range and Standard Range models, which saw a limited run. This is another update included as part of the 2024 Tesla Holiday Update - which really arrived with a lot of unannounced new features and capabilities.
The change is pretty interesting - Superchargers of the V3 and V4 variety can now pre-heat batteries for Model 3 and Model Y vehicles equipped with LFP battery packs. That means those vehicles are able to get back on the road faster when it's extremely cold. Of course, Tesla still advises you to precondition before you arrive, saving drivers time and money.
Max de Zegher, Tesla’s Director of Charging, also commented on the new feature. Essentially, Tesla is inducing an AC (alternating) ripple current through the battery to warm it up. Keep in mind that Superchargers are DC charging. That means it is possible to get a cold-soaked LFP vehicle on the road 4x faster than before, assuming that it didn’t precondition at all and that it is in the worst-case scenario (below 0ºF).
In essence, Tesla is using some engineering magic to turn the circuits inside the LFP battery into an electric heater - and powering that heater through the Supercharger. An AC ripple current is a small oscillation in the DC charging current that generates heat through electrical resistance, warming up the battery. Those ripples are a byproduct of converting AC to DC and back - so Tesla is using the onboard charger to induce those ripples to warm up the battery. Definitely an innovative technique that’s really only possible with the versatility of the NACS connector.
We’re hoping Tesla can implement this across their full lineup of vehicles, but we’ll have to wait and see how it is trialed across LFP vehicles first and if it is even possible on vehicles with 2170 or 4680 battery packs.
Tesla launched two FSD updates simultaneously on Saturday night, and what’s most interesting is that they arrived on the same software version. We’ll dig into that a little later, but for now, there’s good news for everyone. For Hardware 3 owners, FSD V12.6.1 is launching to all vehicles, including the Model 3 and Model Y. For AI4 owners, FSD V13.2.4 is launching, starting with the Cybertruck.
FSD V13.2.4
A new V13 build is now rolling out to the Cybertruck and is expected to arrive for the rest of the AI4 fleet soon. However, this build seems to be focused on bug fixes. There are no changes to the release notes for the Cybertruck with this release, and it’s unlikely to feature any changes when it arrives on other vehicles.
FSD V12.6.1 builds upon V12.6, which is the latest FSD version for HW3 vehicles. While FSD V12.6 was only released for the redesigned Model S and Model X with HW3, FSD V12.6.1 is adding support for the Model 3 and Model Y.
While this is only a bug-fix release for users coming from FSD V12.6, it includes massive improvements for anyone coming from an older FSD version. Two of the biggest changes are the new end-to-end highway stack that now utilizes FSD V12 for highway driving and a redesigned controller that allows FSD to drive “V13” smooth.
It also adds speed profiles, earlier lane changes, and more. You can read our in-depth look at all the changes in FSD V12.6.
Same Update, Multiple FSD Builds
What’s interesting about this software version is that it “includes" two FSD updates, V12.6.1 for HW3 and V13.2.4 for HW4 vehicles. While this is interesting, it’s less special when you understand what’s happening under the hood.
The vehicle’s firmware and Autopilot firmware are actually completely separate. While a vehicle downloading a firmware update may look like a singular process, it’s actually performing several functions during this period. First, it downloads the vehicle’s firmware. Upon unpacking the update, it’s instructed which Autopilot/FSD firmware should be downloaded.
While the FSD firmware is separate, the vehicle can’t download any FSD update. The FSD version is hard-coded in the vehicle’s firmware that was just downloaded. This helps Tesla keep the infotainment and Autopilot firmware tightly coupled, leading to fewer issues.
What we’re seeing here is that HW3 vehicles are being told to download one FSD version, while HW4 vehicles are being told to download a different version.
While this is the first time Tesla has had two FSD versions tied to the same vehicle software version, the process hasn’t actually changed, and what we’re seeing won’t lead to faster FSD updates or the ability to download FSD separately. What we’re seeing is the direct result of the divergence of HW3 and HW4.
While HW3/4 remained basically on the same FSD version until recently, it is now necessary to deploy different versions for the two platforms. We expect this to be the norm going forward, where HW3 will be on a much different version of FSD than HW4. While each update may not include two different FSD versions going forward, we may see it occasionally, depending on which features Autopilot is dependent on.
Thanks to Greentheonly for helping us understand what happened with this release and for the insight into Tesla’s processes.
